Christ Church Cathedral, Dublin (must see)

Although Christ Church Cathedral traces its roots back to the late 12th and early 13th centuries, much of the original building faced structural challenges. In the 1870s, Henry Roe's philanthropy facilitated an extensive reconstruction effort, aiming to preserve the original elements while faithfully recreating the remainder in the Romanesque and Early English Gothic styles.

Exploring the cathedral's grounds unveils intriguing relics of the past. In the courtyard lie the remnants of a 13th-century chapter house, while within the southern aisle rests the intriguing tomb of a knight, albeit with a worn-off nose. Despite popular belief attributing the tomb to Strongbow, historical evidence suggests otherwise, as his original tomb was lost in a 1562 collapse of the south wall. Elsewhere, the Peace Chapel houses a reliquary containing the heart of 12th-century Archbishop Laurence O'Toole, Dublin's patron saint.

Adding to the mystique are peculiar curiosities, including the famed "Tom and Jerry" – a mummified cat and rat believed to have been trapped in an organ during a chase, and the imposing arches on the north side of the aisle, leaning at a disconcerting angle. Descending into the vast crypt, the oldest structure in Ireland, visitors encounter eerie statues of Charles I and II, amidst displays of ornate silverware gifted by William of Orange following his victory at the Battle of the Boyne.

The cathedral welcomes visitors daily and offers enchanting Evensong performances, featuring music dating to the Reformation period, on select days. For a bird's-eye view and the chance to ring a bell, guided tours grant access to the belfry, ensuring an unforgettable visit.
